JAS. nMAnsHconroRATroN, or CHICAGO, ILLINoIsA conformaron or ILLiixroIs@i THEnMoMETER My invention belongs to that general class of devicesknown as thermometers and more particularly to an improved mountingforthe well-known type of glass bulb thermometer tubes.- The invention hasamongits ob-V jects the productionof a device'of the `kind describedthat issimple, comp-act,` attra `:tive,.A inexpensive to manufacture andadapted for the easy mounting or assembly ofthe parts. fbi Moreparticularly the same has as an object the'production of a` tubemounting wherein the tube may be mounted and adjusted to provide propercalibration, and which'tube may be replaced as required and the new tube175i adjusted without requiring the return of the entireinstrument tothe factory for re-cahbration. i

The invention has as a further object the production of an instrument ofthe kind dei scribed that may be easily and conveniently read at adistance and which will not be easily read incorrectly. The inventionhas as a further objectthe'production of a mounting constructed of'asingle stamping or body part designed to protect the tube and 4protectit from'inj ury thereto, the samebeing so formed as to provide for theprinting of the scale directly on the mounting without requiring anadditional scale to ibe attached thereto'.

and more particularly pointed out in the claims.

Referring to theldrawing inlwhich only one embodiment of my device isshown, the main part'fof the mounting consists of a. stamping Jformed toprovide a backfl7 the front face of which provides a space for theimprinting of a scale. At the sides the body" part isoiiset outwardly asindicated at 2 and thence over at 3 and-back as shown at `4v to providea rib, making the part 1 rigid'and also afording a finish. 'At thevbottom the same is 4pressed or formed outwardlyk as indicated at 5 andthen turned over and backas shown at 6. At the top thersame is formedwith the face portion 7 spaced outwardly from the Vface of the'partl land provided with a rib', the extreme edge being turned over asindicated at 9 to correspond with the turned over portion 4 at thesides; v,This gives the` scale. portion 1 and space 7 surrounded orenclosed within the bead 3, 6 and 8. The part may be `formed in anysuitable manner, same` being preferably stamped out or a blank toaV formsubstantially as lshowir'in the drawing. The portion 11, connectingJface portion 1 and*- face portion 7, is provided with va struck-up'portion 10, which leaves an opening l12.`

through which the upper end of the thermometer may be inserted ashereinafter described.` The bottom oroutstanding portion 5 isjpro? videdwith an' opening 15. At this opening L' is arranged a sleeve 16 which isprovided with the flange 17, the parts being held assembled by weldingtogether or by frictional engage- L p ment. It is generally preferred torearwardly oisetthe portion-1 at this point as indi cated at 14 so as topermit the sleeve 16 to be set inwardly and center with the thermometertube.

A thermometer tube 18 provided with the usual bulb 19 is inserted in thesleeve 16 with the upper end extended up through the opening 12. At theupper end l prefer to arl range a felt, rubber or othe-r strip 2O whichmaintains the upper end of the thermometer tube against displacement.The lower end is centered in the sleeve 16 by a rubber gasket 26, thesame being so proportioned as to closely lit theinner Wall of thesleeve, as well as the thermometer tube which passes through the gasket.The tube is thus maintained against accidentalV displacement butV the nmounting is such that itV may beadjusted up by showing the temperatureVof the contents.

VAs shown, the connector 21 isfprovided with a threaded portion 22 andwith a chambered extension 23, the parts being so construeted that thethermometer bulb 19 isV positioned within the chamber. The parts aremaintained. assembled by a screw 24 or equivalent means. Ordinarily thechamber and theconnectoris filledv with graphite, oil and graphite,mercury or other suitable materialV that will' transmit the heat fromthe tubular extension 23 tothe thermometer bulb 19. It will be notedthat the gasket 26 not onlyk secures the .lower end of the thermometerin the sleeve 16, but that it likewise forms a gasket or packing withinthe connector and prevents any leakage between the sleeve 16 and theconnector.

0n the face ofthe portion 1 of the mount-- ing are arranged scale lines28.` The scale lines are preferably made of increased widthl asindicatedat 29, and the numerals or scale readings 30 arranged in thatenlarged space vand in a contrasting color. This permits the readings tobecomparatively large sothat theV n: same are easily ready even from adistance.

Intermediate scale lines between the lines 28 may be provided, butgenerally this is not*` required: as the intermediate readings may bereadily7 estimated. In view` of the fact that the tube is readilyadjustable on the mounting, these readings'may be printed or otherwiseformed directly on the face por-A tion 1, it being my practice to enamelthe body part, l and printthe readings directly on'the enamel generallyafter the enamelv is baked. This affords a permanent scale which cannotbecomev disarranged or out of adjustment; VThe. thermometer tube maythen be inserted and calibration made, the tube being moved up or downand a 4correct reading as- Vtube which may be. adjusted on the mountingso as to give a correct reading and secure it at that point by means ofthe gasket 26 and retainer 20. It will be notedy that the tube liesbelow the faces of thebead 3 so, that it is protected to a considerabledegree. By offsetting the portion 7 the portion 11 may beutilized toprovide the struck-up portion 10 and likewise there is provided-a spaceupon which the manufacturer may imprint his "name and trade-mark orother matter, or.

thisl space `may .be utilized by the manufacturers customer tov providehis identifying marks.V This isvery desirable as the manufacturer of'`apparatus equipped with Ythe thermometers or the installerof apparatusfrequently desire to so mark the thermometer as toidentify their productor work. .lf desired, this 'may ybe applied at the time .of printingvthe scale or may be done by applyingra label to the face 7. It willbenotedl by referringV to Fig. 2 that if a label is applied tothe-face?,the same isiprotected to a more orlesseXten-t by the bead 8 surroundingthe face 7 atthe sidesand top. Having thus. described my invention, itis obvious that various immaterial modifications may bemade in the samewithout departing. from .the spirit of my invention; hence I do not wishto be understood as limiting myself to the exact form, construction,arrangement and combination of parts herein shown andfdescribed or usesmentioned.
